“If you had a script for your life, Leo thinks, you could look ahead to what would come next. You could see what is going to happen to you. You could read all the thousands and millions of words you will say. You will never again have to wonder What should I say or do? because it will all be written there for you. You could know what dumb things you will do. You could find out if you ever will do anything that isn't dumb. But then, what if your script was dull, if you never got to do anything exciting? Or what if something awful was going to happen to you? What if your script was very, very short?”
